AUTOMATIC WOOD-TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 723,809, dated March 31', 1903.

Application filed November 17, 1902. Serial No. 131,625 (No model-3 T0 62% whom it may concern:

Be it known that 1, ROBERT W.BARKER,' a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Automatic Wood- Turning Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for cutting and shaping wood and other material, and particularly to that class of machines in which revolving, and horizontally-moving cuttors are employedto shape the material as it is automatically fed from a hopper.

The construction-and advantages of my machine will be hereinafter set forth, reference being had to the accompanying drawings, in which- I Figure 1 is a front elevation of the machine; Fig. 2, a top plan View; Fig. 3, an enlarged detail View, partly in section, of the carriagemoving device; Fig. 4, a sectional View of a portion of the machine on the line A A in Fig. 1. Figs. 5,6, and 7 illustrate the results or product of the various operations of the machine; Fig. 8, anend view; Fig. 9, a view,-

partly in section, showing the device for moving the carriage; Fig. 10, another end view; Fig. 11, a cross-sectional-view of the carriage on the line B Bin Fig. 14; Fig. 12, an end elevation of the carriage; Fig. 13, a back view of same; Fig. 14, a sectional view of the carriage on the line C C in Fig. 16; Fig. '15, a front view of the carriage, and Fig. 16 a top plan view thereof.

One object of my invention is to do with one machine what is ordinarily accomplished partly by hand and by two or' more machines in the turning of spools or bobbins, and particularly quills. Toau tomatically feed the blocks of material from a'hoppe'r to the spindles,whicl1 receive and rotate them to be operated upon by revolving cutters and fixed knives carried by a horizontally-moving table or carriage during the different stages of the turning until the block of wood has been delivered from the machine a completelyturned quill, is another object sought for and accomplished by my machine; and a further object of my invention is to produce a simple, effective, durable, and inexpensive laborsaving machine that will require but little attention and that will produce with facility larger results than are produced by the machines now in vogue.

Referring to the drawings, 1 is the main supporting-frame; having a table 1, upon which is secured the'support 2 for the mechanism 7, that operates the spindle 4 and the support 3 for the sliding spindle 5 and its turning device'G.

The blocks D, with an opening 01, are placed in the hopper 75 and are fed to the ends 8 and and 9 .ofthe spindles 4 and 5, as will as hereinafter fully set forth. On the end 9 of the spindle 5 are teeth 10, which engage indentures in the end of the block and cause it to rotate. A drive-shaft 11 is jourinaled in the frame 1 and is driven from the pulleys 13 through the operative'gearconnections 12 2*, the latter of which is mounted upon the short shaft 14. A cam 15, provided on its high point with a guide 16 and provided. also with an extended sleeve 17 in conjunction with the lever 18 and the connecting-rod 18,which is pivotally secured thereto at 18 by pin 18 and is provided with a guide 18 having a roller 19, which is engaged by the cam-guide 16, constitute themechanism which give the traveling motion to the carriage 34. The

lower end of the lever 18 is pivotally secured in the bracket 18 in theframe 1, and its upper end is connected to the carriage-lugs 35 by the rod 36, and said lever being operated by the cam 15 through the connecting-rod 18 the carriage is caused to travel back and forth on the support g The spindle 5 isgiveu a slidinglateral movement in order to insert it in and withdraw it from the openingin the end of the block D at the proper time-thatis to say, when theblock is delivered from the hopper and when the quill is completed. This is accomplished by a dish-shaped cam 21, the flange or edge of which varies in height or is broken away, as is indicated by 22 in Fig. 10, said cam being secured to the end of the shaft ll, a lever 23, fulcrumed in a support 24 on the frame and having at its lower end a roller 25, adapted to contact with and roll upon the irregular edge of the cam 21 to operate the lever and cause the bifurcated upper end 27 thereof and the collar 28 which is loose on the spindle 5 between the fixed collars 29 and 30, to give the rotating spindle 5 a longitudinal movement, as stated. To facilitate the said motions of the spindle 5, ball-bearings may he provided at 31 between the collars on the end of said spindle.

On the lower end of the lever 23 is a stud 32, and said stud is connected with the frame 1 by a spring 32, which tends to hold the roller 25 in contact with the edge or irregular flange of the cam 21, thus regulating the longitudinal movement of the spindle 5. the carriage 34 are adjustable bearings 41, having adjusting-slots 42, the adjustment of said bearings being regulated by the rod 43 and the set-screws 52. The rotary cutter 47, provided with knives 48, is mounted on the shaft 44, which is journaled in the said bearings 4O 41, which are in turn secured to the sliding carriage 34. As shown in the drawings, particularly in Fig. 16, the rotary'cntter 47 and its shaft 44 are mounted obliquely across the carriage, its axis of rotation not being at right angles with the sides thereof. The pulley 45 is secured to one end of the shaft 44 and t he rotary cutter is driven by-the belt 46, which passes around said pulley 45 and under the idlers 38 30, which are mounted on studs in the bracket 37. A tool-stand support 49, having extended arms and a bracket 51, is adjustably secured to the carriage 34 by screw-pivot 53 and is provided with slots 54 in the outerends of the arms 50, which permit of the adjustment of said support, and the set-screw 52, passing through the bracket 51, is adapted to hold said support firmly in the position desired. To the tool-stand support is secured the tool or knife carrying table 55, which in the drawing is represented as carrying the tools or knives 56 57 58 60. The knives 60 are carried by the bracket 59 on the tool-carrying table 55. The

' quill F (shown in Fig. 7) shows the parts ff f f f, which are cut by the respective knives 56, 57, 60, and 58. The block I) While being shaped or turned into the quill F is held steady by the lever 62, which is provided with fingers 62 and which is secured on the arm 61, which is fixed to the bracket 59, and by the lever 65, which is pivoted on pin 64 in the arm 63 and is pressed down by spring 67, so that the outer end 68 of the lever 65 passes over and behind the quill. When the carriage 34 moves outwardly, the lever 65 and the lever 62 withdraw the finished quill when it is released from the spindles 4 5. The arm 69, which is secured to thecarriage 34, carries a table 70, which is provided with a cut-out portion 71.

66 is a stop for lever 65. A pin 72 is secured to the arm 69. The hopper 75 is secured to the rails 73 and 74. A spring-pressed holder 78 is secured to the pin 77, which is mounted in the bracket 76, and said holder is acted upon by the spring 79, which presses it downwardly to engage the lowermost block D in the hopper 75 and holds the block until Secured to 7 the table moves forward under the block, passing on either side of holder '78 by reason of cut-out portion 71 in the said table carrying the said block forward and pressing the said spring-holder outwardly until the block is received in the angular upper portion of the lever-arms 80,when the said spring-holder upon the return movements of the table 70 is permitted to engage the next block D in the hopper until the operation is repeated. The arms 80 are pivotally secured at their lower ends on pin 81 to the sides of the carriage 34. The angle-shaped parts on the upper ends of arms 80 are indicated in the drawings by the numerals 82, and 83 is a recess in the carriage 34, in which the said curved lever-arms 80 are permitted to rise and fall when required. The raising and lowering of the curved lever-arms 80 are accomplished by the joint action of the sliding carriage 34, the lever 84, and the lever 86. The lever 86 is provided with anelongated slot 87, through which passes the shaft 89, which is secured in the bracket 88.

In the drawings, D represents the rough block; d, a hole through the block; E, the block after leaving the rotary cutter; e, the tapering portion of the block; e, the straight portion thereof, and F the finished quill.

The operation of the machine is as follows: The carriage 34 moving outwardly, the table 70 moving at the same time presses the springband 78 outwardly, releasing the lowermost block D in the hopper 75, which falls onto the table 70, from which it is delivered to and received by the upper angle-shaped end of the curved lever-arms 80, which arms carry the block under the levers 65 and 62 to the point where the sliding spindle 5 enters the hole d in one end of the block, pressing the block onto the end 8 of the fixed spindle 4, whereupon the carriage 34 brings the rotary cutter 47,which is operated by the pulley and belt 45 46, up to the work, and then the knives 56, 57, 60, and 58, as shown, until the quill is finished. When completed, the quill is removed by the levers 62 and 65, as the sliding spindle 5 is then withdrawn from the quill by the operation of the lever 23 and cam 21, the forward movement of the carriage causing the said levers to give the finished quill a push.

This machine in practice has given satisfaction, and the only attention required is to see that the hopper is kept supplied with blocks. All of the parts of the machine act conjointly and automatically throughout the various stages of the operation and turn out several thousand quills a day.

It is obvious that the machine accomplishes the work hitherto performed by several other machines, which required several operators, and is a labor-saving device that increases the product and lessons the cost of production.

I do not wish to limit myself strictly to the construction shown, as alterations may be made both in construction and arrangement without departing from the essentiaLs'pirit and scope of my invention.

With this description of my invention,what

I claim isd 1. The combination of the frame, and ahopper, having a downwardly-extending spring-, pressed holder, with a reciprocating carriage, arms connected with said carriage to receive, release and carry the lowermost block from engagement of said holder, a table, secured to and moving With said carriage to pass under and act as a temporary support for the remaining contents of the hopper, and means for reciprocating said carriage, substantially as set forth.
